im looking at getting a new bow too,and having shot them all.which i highly recommend.its between the drenalin or the guardian im leaning towards the guardian but dont think you can go wrong with any newer bow.i personally didnt like the feel of the hoyt either the vectrix or the trykon,but that is just personal opinion.but i definitely recommend shooting them before you buy one.one or the other might feel way better and then you wont have any choice to make.
