@OP. I think it's pretty clear that there is no 'best', otherwise we'd all be recommending the same string.
There are quite a few good ones and they're all a bit different from each other.
Try some sets before committing to a reel.
Except for Isospeed Baseline. I've never seen sets of that.
I have reels of Pro's Pro Vendetta(PLII clone), Blackout(BlackCode clone), Ichiban Spin, and Plus Power(SPPP clone) as well as Iontec Black and BHBR17.
They each have their strengths and weaknesses, as do high priced strings.
