Mao,
The R29 is a bad ass crossbow!

I'd say you did very well for yourself.
As for your broadheads not making an "overwhelming big hole", it's all about the shot placement, brother. You put the shot where it needed to be and that's how you got it done!
$29 for a 3 pack is good. Ravin has 3 different choices (for a 3 pack) and the only difference is the ferule material. Titanium ferule is $90, Steel ferule is $70 and the ones I purchased is Aluminum, at $50. (These prices were at Bass Pro, in Rossford, Ohio). I guarantee you, that once these broadheads are gone, I'll be switching back to Slick Tricks.
