I also liked Avalanche & Blocker. They were my first two BF2000 figures. They were individually carded over here in the United Kingdom. I guess I just liked them and perhaps I wanted someone to drive the snow cat, since frostbite was broken and i buried him in the garden :-) (I was 8)
So my thoughts on BF2000. I think if they were to redo the characters. For the most part these have helmets. I'd like to see Avalanche, Blaster, Blocker, Dodger and Dee Jay all with removable helmets. Leave out Maverick and Knockdown. I'd have blaster in the green again but darker green more like the 2001 ARAH Colours. Avalanche could be again the snow vehicle driver. Blocker. I didnt think was much wrong with the first one. I'd probably change the orange to a more tan colour instead.
I'd like to see an improvement to dee-jay with him decked out in black & grey colours of the 1991 Sci-Fi figure.
And No Pink Rifle this time!!
I don't know how popular this would be. I remember a few of the BF2000 figures being peg warmers for quite some time in toymasters and toys r us.. so its difficult to say.
