My gf picked up a 189dollar browning micro adrenaline. OK bow, slow, she's already pulling within 2# of it's max weight and would like the option to go higher (she's pulling 48lbs it goes up to 50 maybe 55 with work). She knows this is a kids bow, wants something more high end, tired of the hand shock and low efficiancy. she's shooting 185fps, the kid pulling 40lbs is shooting the same speed..slow bow. I was seriously thinking about the pink Marin tigress. Few questions.. 1) is this bow still readily available? 2)Can I get 55 or 60lbs limbs? 3) is this a segnificant step up in class. I'm shooting my used orion, my first bow and liking it. but I don't feel upgrading is a bad idea since she payed less than 200 for a bow. She loves it and shoots every day she really has just outgrown this equipment at this point. Opinions on this idea or other options?
