Mike...which reels are you interested in?....Both the Tetons and the Orvis reels can easily be converted to a left hand retrieve...they are currently right hand retrieve....the Orvis Battenkill reel and spool are perfectly sized for a 3/4 weight line setup....but the Tetons would work as well...you may just need to add a bit more backing...but not that much more since they are a Large Arbor version...Teton reels have a fully sealed drag while the Orvis reel has a click/pawl design...there is a big difference between the weight of the reels....my personal opinion the Orvis reel balances very nicely with a 3 or 4 wt rod...nice and light...any other ques please let me know...thanks for looking...
