The extra top cross is fine, they actually have an extra double grommet for that. I sometimes do that for people who frequently break their strings at the top of the string bed, since that gap is a liiiiittle bit bigger than usual.
I do it all the time - the MX pattern is terrible for breakages at the top of the mains. In fact, it's a terrible pattern full stop, IMO.
Yup, I've had very good players break their strings there often, adding that cross does wonders. I hate the pattern too, takes too much time (actually I hate all 1 piece patterns, hate dealing with all that string lol). But Kwun did find that this pattern was more playable, so it has to have a little something...
If I saw that after paying $20-30 for the job I would ask for a refund or get it restrung. It looks kind of silly and in an area where you might mishit and break the strings.
I string for a frequent top main breaker and his rkep pro9000 seems to have just as big of a gap as my mx80, so im assuming it'd be okay to add one more cross. do you still limit yourself to 28 lbs on that one extra cross or do you go lower?
28 is fine IME, then fade in 1 lb at a time - it's a very high cross, but not much higher than the top cross on a Z-Force.
For most gamma machines with badminton top support, those crosses are no problem. However, when I did not have those, I would tension the string with a curve. That string is only there to provide additional support to the mains at the top, so the resulting tension is not as important. Be careful though, because if your string breaks there, you'll want to shoot yourself, or just tie up without the extra cross
On those occasions where the 12 support forces a bend, I just tell myself that the cross in question wouldn't even be there on most rackets, and go with the bend. On my machine, the deviation is no more than a quarter of an inch anyway - nothing to be overly concerned about.
haha yeah I've thought of that, if it does happen, I'll just tie it off without that extra cross thanks for the info guys
