Roland Banks after 4 Path to carcosa scenarios

I have been very happy with the way this build of Roland banks has performed so far. While the party of 3 has been working well we ended up getting no XP for scenario 3, the unspeakable oath... However we rocked the asylum and gained 7 XP. This is what I have upgraded to thus far, with 1 XP left over. I will next upgrade my other .45 automatic and then... well then what??? Suggestions???? we have 4 more scenarios left in Carcosa to go... Thanks for looking
