Going smaller is the answer but it's not just the size of the guide, an even greater factor in eliminating guide wraps is distance of the first guide from the reel.
Moving the first guide out uses the effect of the payload straightening the line (and decreasing the contact angle of the line to the guide) to smooth line flow. Because the "coils" are smaller in diameter and longer in length the further from the reel, one can use smaller guides.
So, I am a big proponent of smaller guides on spinning rods using braid
when matched with reels with the proper spool profile. Again it is best to be smaller rather than bigger; for top braid performance reels should have a small diameter (and in a perfect world, long and shallow). RIfoosball is in a better position to eliminate guide wraps with the use of the smaller diameter Penn 5500 then if he was using a big Greenie.
Casting performance is a fluid effect dependent on each component, reel, line, rod and guide design and layout and the interaction between them. If one wanted to build a drag racer it seems pointless to me to do the frame, transmission and engine work and then put a UPS box body on the chassis. Point being, blaming RI's problems on PowerPro is misapplying blame. Everything needs to work together and while a change to Fireline might lessen frequency the fundamental problem remains.
To the OP; if you would like to be even further confused there is another discussion of guide wraps on spinners and guide design and location over in the Rod Building Forum;
