Need help with Mantlet Respec

OK guys, I need some help here. We have a Freespec coming on December 7th. I already have one on Mantlet, so it makes sense to use it before then (since you can have only 1 per character at any time). The help is I need to know what direction to go with for Mantlet.

When we get together with our "Big 3" characters, he plays two roles. First and primary role is aggro management for the team. This usually means trying to keep the heat on him so Orleans and Cacaphony don't get more than they can handle. Lately I've been a bit out of practice Tanking, which isn't such a big deal since Orleans and Cacaphony are much more durable in their old age then they were as young heroes. However, the second role Mantlet fills in our trio is that of laying down the damage and "soft control" with the knockback/knockdowns. Orleans pushes out great damage, Cacaphony does as well (but is somewhat hindered by the scaled damage for Defenders), but it seems like the damage Mantlet dishes out is a key element as well.

So, I'm at a bit of a crossroads. Looking at a respec'd Mantlet that can perform at Exemplared levels, I'm faced with a tough choice. First route is to focus on the "Tank" aspect of the character. Aggro control, defenses/resistances, and (perhaps most importantly) adding Psi defense/resistance with IO's and set bonuses. I have a draft build that drops Punch, Combat Jumping, and Resist Physical Damage and swaps in Boxing/Tough/Weave. This means one less attack in his attack chain, but with IO sets generating substantial Recharge bonuses over SO's, this may not be an issue (i.e. the chain will tighten up so the extra attack is not needed to fill it out). By 4-slotting Impervium Armors in Mantlet's Resist Damage powers, he gains up to 9.4% Psi defense. Since Unyielding has a -5% defense to all, this would mean his Psi defense would start at 4.4%. The Steadfast Unique adds +3% defense to all, bringing it up to 7.4%. Weave adds 5% unenhanced, around 7.4% slotted up. This brings Psi defense up to about 14.8% Scirocco's Dervish 6-slotted in Footstomp gives an extra 3.13% Psi defense, bringing it up to 17.93%. Problem is that this gets expensive and Mantlet only has 8M in the bank with probably 3M tied up in enhancements slotted (can be sold during the respec). Since Psi is the single biggest hole in the Invulnerability set, this would make him essentially able to viably Tank anything in the game for the team.

The other route to take is to focus on combat capabilities. IO set selection would be focused on +damage set bonuses, +Recharge, and endurance recovery/regen to offset the lower resistance/defense values in the build (compared to a more "Tank" build). Attacks would be six-slotted early to maximize exemplared performance. While I could probably squeeze in some Psi defense/resists, it would not be as robust a build.

Question for you guys is would you rather have more Tank, less damage or more of a Scranker build leading the charge? I could probably find some middle ground as well, but wanted to see what input you all had first...
