ISOSPEED 15L or 16? for Wilson Steam 99s

[PhilStar!]

I need a durable but playable thick string for my wilson steam 99s.

Have someone tried ISOSPEED Baseline 15L and 16 with it, and suggest which one is better suited for it.

I know the 15L is a little bit thicker but there's not much customer reviews for it. I would like to see if the thinner 16 was still durable enough yet performed a lot better than the 15L to decide to get the right reel.

By the way, these ISOSPEEDs are traditional polys, they not co-poly, is that correct?

I am also considering Genesis Black Magic 15L but it's about 1.33mm, which is not much thicker than any 16 G string (1.30mm). If anyone can compare Black Magic 15L to the ISOSPEED strings, please share, thank you!

By the way, for those who have Wilson Steam 99s and are using 15L strings, does the extra thickness of 15 / 15L over 16G compromise "feel" dramatically?

If it's only a small, subtle difference in drop in feel, then I would still consider getting the thicker 15L reel.

I've only used 15L once ( Prince Topspin Plus Syn. Gut ) in a 16 X 19 String pattern racquet, and I hated it. No feel whatsoever.

But I've never used a 15L Poly in a very open string racquet so wouldn't know how much feel is compromised when switching to a thicker string.
