Lix bomber conundrum

Problems in bombers in lix:

Problem A. bomber1 (no-fling) is very similar to bomber2 (fling)
Problem B. Timers are a nuisance in singleplayer mode, but add fun to multiplayer mode.

Propositions to solve:

Prop 1. Remove bomber1 from both game modes.
Prop 2. Remove timers for both bombers from the singleplayer mode only.
Prop 3. Remove timers for bomber1 in both game modes, no other change. (It's assumed that bomber1 would then be used for singleplayer mode by convention, and bomber2 for multiplayer, but level designers can break convention if they please.)
Prop 12. Both Prop 1 and Prop 2: remove bomber1 from both game modes, and remove the timer from the remaining bomber (bomber2) only in singleplayer mode.
