Man, are you double dipping on your HaterAid? I think every color Spro has brought to the market is pretty Good. As I have stated before multiple times, It would be great if Spro released versions in Wart colors even though I think that color can largerly be a con game we play on ourselves.
Bill design for deflection, wobble, bouyancy, profile, and the depth the bait runs are all more important than a squiggle here or there or a nuance in the shade of green or Brown.
I'm sorry you've had so much trouble with RK Crawlers breaking on you. I've heard of this happening, but so far that bill breakage problem has never happened to me. I'm not thinking the bill breaking of RK's is any worse than the inconsistencies of the original warts.
I grind Squarebills in <6 FOW. I grind warts in 4-8 F. RK's get thrown in >6 FOW. Works for me.
