Yeah, I read about the Raider- just left my initial conjecture.
Honestly, as we don't know when
Raider's record sheet will be published, I would go with the
Storm Raider if I were in your shoes. These 'Mechs are quite similar.
For the TBolt, I picked the lower end of the Merc RAT which was the -7M. I also realize the BK should be one of the new FS models but eh . . . Mongoose improvement makes sense with the Raider's known factional differences, I just did not look up the named mechs much.
The description of her
Thunderbolt states that it has ER PPC and ER Large Laser with LRMs. As I like T-bolts, I know that -10S is the only variant that fits.
Last year - after
TRO:3145FS was published - I used record sheets to recreate those
Black Knights for my MegaMek, so I know that -3B is the only model with ER PPCs and small lasers. I don't like this particular model too much, but I know its stats.
The WizKids' fluff for
Mongoose II quite clearly describes upgrade from -266 to -267 model, etc.
Why the Shadow Cat 4 rather than the HAG version? Any fluff for the character or dial I missed?
Because his 'Mech uses EMRG "Captain" Gauss Rifle. I remember from
TRO:3060 that those weapons were used on
Highlander IIC and that they are standard Gauss Rifles firing solid slugs. And if the 'Mech uses a pair of LRM-10 launchers, then it must be
Shadow Cat II 4.
