I would suggest going the sentry drone route. Besides being the flavor of the month it is very easy to multi box. Just have your alts assign there drones to the main character and you have the dps of 4 ships while only flying 1. Also railguns have been largly improved over the last 2 expansions so gal is a good route to train. This would give youe Myrmidons, Ishtars, Domi's for drones and thorax , mega for rails / blasters your choice. Also there armor based so it will fit in well with the WH ops. Just a few thoughts from an eve vet.
