The first thing to work out is what you weant to do with your 'top end' attack. The two classic chocies are gravity well and tykens rift.
The lat is better for team play such as STFs and esp. PvP becase the debilitating effect applied to the target benefits everyone. The former, gravity well, can do an awful lot of damage if well timed with other debilitating powers that reduce the targets resists and defence.
The thing to bear in mind as a sci is you weapon dps is never going to be what it might be, although this is less fo a probelm with a BoP.
Try t build something that really capitalises on spike damage and goes in two phases. The one being your big science attack and the other for gun/torp damage on the disabled target. BoPs are glass cannons without equal so you nede to get in do some heavy damage, then bug out, cloak and start again.
Such is my experience, and I would add as a player I was so apallingly bad at it that I now fly Battecruisers
