Not that much room for a tank SPECIAL if you roll with 10LK and high int.
If you pick 8 int you will be capable of hitting 250% SG + 150% in two secondaries. Making it a very viable character to level after the softcap.
This does mean that you won't have to much room for other SPECIAL. You can either rely on having a squadleader that grants defensive buffs or roll with 1 CHA and get yourself a decent STR, END and AG. While AG is fairly usseles it does offer you knockdown resistance. meanwhile STR offers you knockOUT resistance. So pick whatever you consider more important and go with that.
It's probably best to roll with enough str to handle your pistols without weapon handling, and ensure that you don't go <5 AG or something close to that. End can be sacrificed a tad if you dont mind losing out on 20-40hp compared to others.
Something like: 5/4/5/1/8/7/10 could work or: 7/4/5/1/8/5/10. Yes that is much more STR than you need for your weapons, but that doesn't mean much in a gameworld where a knockout results in your death 9 out of 10 times. Knockdowns are dangerous for smiliar reasons.
Last but not least, if you have a good squadleader that enjoys defensive buffs, you could roll with: 3/4/5/5/8/5/10.
Do not underestimate charisma, it can be considered OP if you apply the right buffs in the right situations.
