String @ your comfortable tension, everybody is different. And just a heads up, those three strings are thin strings, so comparing to your BG65, durability of all those new three strings your are going to use is not that good. But friendly to play with.
All three are very nice strings, thin gauge with very decent repulsion. There are differences between the strings but I think you wont go wrong with any of those.
ZM 62 has the the best tension holding ability and has harder feel than the other two strings. Very nice sound and power. Due to its ultra thin gauge it is also one of the easiest string to break.
BG66 Ultimax has the best feel when freshly strung IMO. Overtime it loses tension and feel, gradually becomes "dead". Also very nice hitting sound. It is rated "medium feeling" by Yonex but feels softer than NBG98 (also rated medium feeling by Yonex).
NBG98 is a very powerful string and has the best durability of these three strings, though not stellar when compared with thicker strings like NBG95 or BG65. A bit numb feel and a bit slippery.
IMO the uniqueness of each string are better shown at higher tension. But of course, do choose the tension that is the best for you
I have a Yonex Aromtec 700, which I bought and strung 4 years ago with yonex bg65 string.
I wanted to restring it but didnt know which one to get so I bought the following 3;
I have a few questions please; I want to compare between these three strings to figure out which string I will use in the future raquets.
Should I string them at the same tension? I'm planning on 23Lbs.
Or due to the difference of the strings should I string them at different tensions if so what are they for the above three? I consider my-self an intermedeate player.
I will by in the next 2 months one of these raquets after I get a chance to use them

Thank you very much
the best way to try out the strings is to get a few of the same rackets with the same spec, then string each of the strings you've listed on those rackets at the same tension. that way, every variable will be constant except the characteristics of the strings themselves.
i did it with bg66, gosen66, and zymax62 and it was fun!!!
