I throw both the R-pro boss and the aviar. I like them both. They have their place to be used. I think the R-pro plastic is a bit better than the pro plastic. It is grippier, but that just makes for a better grip.
Yes, I bought one the other day ...145g it flies fast and straight and I really love it. I haven't got the hang of throwing it side arm but back hand its a real nice flier. As for the floppyness, its has too much rim to stable it. I have a dart too and I know what you mean, very felxable. Oh, and I was going to dye it ...it dosn't take the dye. It just wiped right off.
hey i have a r-pro boss now. its a 144wt. that thing flies forever. as stated earlier, it flies uphill wonderfully. it has a few dinks on the edge now, and only used half a dozen times. so i dont believe it will last long either. i have short fingers and finally a speed 13 disc i can chunk. yahoo.
