Okay:

I agree, the tracks (& sprockets) may be overkill, and perhaps the suspension arms (306) can be bought 'if/when needed' (or replacement Tamiya stock arms)

Some of xf62's tweaks are interesting, but I'm not bullet-proofing her for battle, so a few of those choices are extraneous:
- chassis reinforcement panels (327), bogie wheels (316) and idler wheels (319) are overkill, and I like the stowage baskets (309) but at 72.00 euro, I'll try to solder 'em up myself

On the like/want list: (prices in euros)

- the idler adjuster (310) at 34.95 is wanted (really love my one for the M26A3)
- the MG3 & mount (026) for 21.50 is sweet, to complement the ones on my 1A4's (may even get a few to replace the plastics)
- the tow hitch (304) is economical at 10.25; the mirror pack (302) at 10.60 is nice; and the barrel traverse lock (321) looks nice too at 9.85;
- the detail kit (301) of 4 shackles, bolts & hull mounts, 2 headlights, & 2 complete tow ropes with end loops for 31.50 sounds good too;

- the bearing bolt set (317) at 101.53 looks interesting, but can it be run with ball bearings? as do the torsion mounts (311) at 60.53 (do I need them both?)

Further opinions?
