the difference maybe in the % distortion of racket frame,
but i wonder which one should be applied according to 10% higher on cross.
27 + 10% = 29.7 ---> 29.5 or 30??
28 + 10% = 30.8 ---> 30.5 or 31??
which one is safest?

The best way is to try both and take photos for us to examine .

if i have two same racket, one unstrung, i can examine my self and tell the result.
but unfortunately i dont have two, so from your experience which one better?
because the stringer's machine just do in incremental 0.5 lbs, some just do at 1lbs max. If possible with the machine, i'll string exactly 10% higher on cross. But it's not possible.

well i say it depends on the stringer, if its done by any of the top caliber stringers here at BC, you'll be safe...

what i meant to say is that, at that tension, you need a very good stringer (BC'fer no less!) 'coz it becomes reeeeally dangerous (frame breakagewise) as the tension goes high. it is important that the stringer really knows what he is doing otherwise, you might end up with a distorted frame.
now, as for the difference in tension (cross vs main), like what kwun said, i would also be surprised if you'd be able to tell the difference (in performance or whatever) with a .5 pound increment...peace bro!

I know! Send your racket to Master NGP and have him string it .

Usually a tension scale has markings, with 1lb and 1/2 lb lines or markings. In between any two lines or markings is 1/4lb. So I don't quite understand why your stringer's machine can only set tension in 1/2 increment only.

Sorry little bit out off the topic.
Is oval racket need to be stringed main<cross?
or it can be stringed main=cross.

Yes it makes no difference whether it is oval or iso. However, oftentimes the stringing quality is not up to standard, nullifying the 10% tension difference. More racquets are distorted from poor stringing practices than from not using the cross>main tension. It makes me want to cry!

That's true. Especially in Indonesia. I don't know about other countries.
Here, I have found out that the stringers are learning by doing. They do not get right information/training, or at least searching a reasonable sources for reference.

most of them will string main=cross or even main>cross. So sad

1/2 more precise, 1/4 between 2 line marking, so it isn't precise as 1/2 (which marking meet marking).
and also the scale between two line is so close.
So Eepak, what's your suggestion? which one is better?

Does the machine have two tension devices? One is the tension scale and the other is the rotating knob that turns and moves the tension scale. The rotating knob has markings in 1/2 lb with huge gaps in between. If you use this knob you can even adjust the tension to 1/8 lb.
My suggestion is to set up your own qc control. You do this by placing your unstrung racquet against a wall and use a thin pencil to trace a 6" outline of the top of your racquet on the wall (stick a piece of paper on the wall). You then ask your stringer to string your racquet at 27lbs for the mains and 29 3/4lbs on the crosses. After stringing you place the strung racquet against the same spot on the wall and try to match against your earlier trace. If it is in perfect alignment, that is you don't see double lines, then stick to this stringer the next time. If not, go to a new stringer until you find one that can do the job. BTW oval racquets will require different stringing practices to iso racquets for that perfect 100% distortionless stringing. What works for one will not work for the other.

looks like i have to try it my self to decide which is better.
btw eepak, your suggestion is good, after string i'll try to match w/ the frame.
find another stringer is no good in my place, every stringer that i ask always do same tension on both cross and main. So i must request myself to do 10% higher on cross.

btw i already asked him to do main at 27 and cross at 29.7, but he said he could only do increment 1/2 lbs. haeeee...... he asked me wheter 29.5 or 30??
sometime i do below 10% at 29.5 but sometime more than 10% at 30, never try to match w/ unstrung one.

so it really should be exactly 10%?
if you ask me, 27x30 would be fine....

this borderlines OCD...
