@barnes...have tried SG/Poly and Multi/Poly. Not as much control or spin compared to gut mains imo. The synthetics seem to be shredded or notched differently from natural gut based on their structure. I found solid core SG and multis work better as a main with polys. Multis composed of many, many fibers seem to shred in a manner that increases friciton.
That being said my son and I had some interesting results with TNT multi mains and poly crosses. Juts not as nice as natty gut.
@mrmo...have not done PHT/VS....seems like a waste of expensive gut since most of the feel comes from the mains. Would probably be no different than poly/multi, not really sure. Maybe others who enjoy poly/gut can chime in and provide their experience.
