Welcome to the superior mod (/s)! Your bot looks pretty solid, but there are a few things I would change:
I think blades are better in this situation, due to only 1 side of the weapon being needed
The wedges are useless. Only the centre AP of a skirt hinge is actually wedgy, and yours is too short to be useful IMO.
A LW only needs the yellow z-tec IMO. Motors are really damn powerful in this mod.
The motor is really exposed
It has some good things about it tho:
The armour panels in IF are really strong, so the front of your bot is well protected
You've got your batteries sorted first try, though maybe a black + pink would give more juice? Not sure on the numbers.
You made use of the free ballast weight, which is good.
Not to toot my own horn, but you might want to take a look at this bot, which is pretty similar conceptually to yours (despite being a hw):
Note how the weapons are behind the frontal protection, the weapons are as close to the ground as possible and I have 2 long wedges (which may not fall within the weight constraints of your bot). It's also worth experimenting with treads, they're pretty good in IF. Their length gives a lot of stability and the treads are really tanky (no pun intended) and can take plenty of hits. Notice how even the HW doesn't need supoer powerful motors for gutripping. I found having multiple weaker motors with more weapons increased stability greatly while keeping damage. You might want to consider using 2 yellow z-tecs on your bot if thats an option, or using 1 with more weapons if it's not.
As for your questions, consider IF as DSL:Promod. Most of the same bot types are popular (though flails aren't very common), and everyone builds DSL-S.
