Thanks for all the help people, it's a steep learning curve for me so thanks for being non-judgemental and generous with your knowledge.
I think my rough plan is to spend more on cabs on the whole. I've contacted Alex at BF so see what he recommends too, but maybe try to get hold of a Barefaced One10, see how I go and whether need to double up in the future, or maybe just a Two10 if I can find one.
And look for an Ashdown RM 500 or OriginAL, then maybe invest in an ABM later on, (and hopefully keep the class D for spare/portability.)
