well, 3

first off, the damage bow, ive got a perfect 5/1 vamparic mod, and marksmanship +1 20% mod

, mostly intend to use these for spamming barrage, and other spamish stuff as a r/mo, or as a r/w with flail, which would be the best bow type to go for?
shortbow is consistant, recursive is quite nice, flatbow is ok, but the miss rate and high arc and long flight time arent so great. i use a zealous one already for barrage

hornbow might be the joker, lower rof but 10%AP might swing it. im intending for this tobe my "nuking" bow, as i already have various bows and mods (+al and hp etc)
i also have a daze/silence lengthing string, so im thinking that would be sweet for a interupt build?, broad head arrow and concusion shot are expensive, so a recursive or shortbow with +5energy would be ideal?
finaly my other ranger is a trapper/beastmaster, would the wintergreen bow be the best (apart from longbow for pulling

) for someone who will only invest pocket change into marksmanship (15^50 inscription, or 5e) with some extra armour and some random string i got spare like fire, AP. i dont think the zealous or the vamparic is worth it as ill just be attacking 1 foe, and with the chances to miss etc, not really worth it..
For barrage, I prefer a recurve or a flatbow. Yes, a hornbow does squeeze out that extra 4ish damage per hit, but it loses out on arrow speed and range, making it not quite as attractive for interrupting or staying out of the fray. Also, for PvE, a hornbow just doesn't find as many uses as other types, and ends up wasting inventory space most of the time.
I wouldn't really bother with a 20% +1 mod. No matter how far you stay back and how good your frontline guys are, you're going to take damage. Better to be able to shrug that off instead of dealing 1 extra damage per hit.
I have a 15 over 50 silencing recurve for dazing builds. I suppose a +5 energy would be helpful since you're relying on others to do damage, but I'm lazy and uncreative, so meh.
I used to use a shortbow most of the time, but it's fairly important to be able to attack from further away, for hitting things on or from cliffs, or being able to interrupt the backline caster without running into a big mob. A flatbow with rtw or fav winds will outperform a shortbow in almost every case. Besides, monsters don't dodge the arrows much.
For a beastmaster, I hear that a staff works well and allows you to control your pet better, but I suck at that, so I use a zealous flatbow. Helps keep up the energy and sends the pet in from a long way away. Give both a try and see which works for you.
I would suggest a +20 energy staff as well, for trapping, touchies, and beastmastery. You'll get more mileage out of it than you'd think.
