I don't shoot the Maximas (too pricey), but I have gone almost exclusively to the Carbon Express Terminator Hunter 4560. Far less expensive than Maximas, just harder to find since they have been discontinued. Too bad, they have great base GPI and were/are possibly the toughest arrow I've come across, bar none. I buy them when I find them and have quite a stash. BTW, I think the CX Rebel Hunters would be a great alternative, with a nice base GPI to work with.
I shoot them 29.5" with 3-4" vanes, 7" wraps, standard insert, 125 grain point which comes out to 500 grains or so. These fly great in all my recurves that are 50#-55# at my 28.5" draw. Works so well I see no need to add more weight, but if I wanted it, they fly well with a 50 grain brass insert, but at a loss of speed & trajectory.
I also have CX Terminator Lite Hunters in 6075 (these are still available). I shoot these primarily from my 60# Reflex Caribou, but set up the same as the 4560's but cut to 30" they work just peachy from my recurves. If anything, being a bit stiffer they are even better with a broadhead up front. Weight at 30" is about the same as the 29.5" TH's.
I've had good luck with Cabelas Stalker Extreme 5570's, which are Beman ICS sold with the Cabelas logo. With a GPI of only 8.4 they need a fair bit of extra weight to get them to 10GPP for Trad, but are very good and raw shafts are only around $50 a dozen...
I think you'll find that with carbon arrows, length affects spine more than up front weight, within reason...
