They are very heavy and not very durable I have not tried the new small ones but the 4" ones are horable took them off after about 5 mins of shooting them. Try vanetec better then blazer or quickspines!!
I have shot the 3" quickspins for two years and have had great results with them. They fly even better with a wac em broadhead attached. I see that they have made them in the 2" now. I have not tried the 2" quickspins. However, you can't go wrong with either the quickspins or the blazers IMO.
i'd get as far away from anyhting thats not a 4 inch regular stock vane ie. vanetec. they are the ultimate vane for all around shooting at any distance and for any arrow
I have some blazers and the 4" quickspins and I think they shoot awesome with montecs or wac ems. All the way to 60 yards. They weigh 10g more than the standard vanes tough. my arrows weigh 498g 31 in long 100g head.
