So I need suggestions for cut on contact or maybe maybe maybe hybrid broadheads for a 45-53# Hoyt Carbon Spyder Turbo with 24.5" draw length, and I'm shooting Easton FMJ 460 spine deep six arrows.
B&A,
You have already received solid advice from Jeff and others.... My advice comes from 2 sources....
1) Personally experimenting with all sorts of arrow/broadhead builds for my wife who shoots 52lbs. With a 27.5" draw length.
2) Witnessing the results of hundreds of bow shots taken on African game with lower poundage set-ups.
My advice is a combination of what Jeff and Bullthrower338 have mentioned in that you need to consider both the broadhead style and your total arrow weight to expect maximum penetration from your lower poundage set-up. Broadhead style is a huge part of this equation. However, your total arrow weight and the percentage of front of center weight your arrow carries are even more prominent factors in achieving the maximum amount of penetration from any lighter set-up.
I realize that you have concerns about arrow speed, but please understand that arrow speed is not nearly as critical as momentum. You might be surprised to learn that an additional 100-150 grains of total arrow weight really doesn't slow the arrow down nearly as much as you would think, but the results equating in penetration are massive! My wife's African arrow build is a total weight of 640 grains with a 200 grain, 2-blade, single bevel Helix broadhead. The arrow has approximately 23% of its weight front of center. I had her previously shooting all sorts of broadhead and arrow combinations, but the common denominator that changed the game was going to a heavier arrow, with a heavier broadhead and an overall heavier foc build. She has now gone from bouncing off shoulder blades to crushing through them.... Less than 10" penetrations to complete pass-thru's on game as large as kudu and zebra.
Regardless of the total arrow weight, with your lower-poundage and draw length, I would personally advise avoiding expandable broadheads all all costs. I don't like their performance on any set-up let alone lower poundage set-ups where you simply cannot generate enough momentum. They act like a huge parachute upon entry... That is if they do not break, bend or deflect beforehand.... Any compact, strong, heavy duty, fixed-blade design that flies true from your set-up should perform well. I like 2-blade, single bevels for lighter poundage bows, but any head designs like Slick Tricks, or Muzzy MX-3s will also perform well. Don't be afraid to beef up your total arrow weight and increase that foc! The results will amaze you...
