In following guide (and "guide" is a big word - it won't be as detailed as similar guides) I will walk you through my idea of Gila viable for Alpha pilots.
The reason for this guide was lack of concrete information - we always say "Alphas can use Gila for T3", but I haven't seen any fit, guide or testing done to confirm that. It might be available somewhere, but instead of looking I decided to do this myself :) Fun!
Fit description
Fit is based on Povertila - most commonly used Gila for for Abyssal Deadspace. The fit claims that it can run up to T4s, but doesn't mention pilot skills - I assumed minimum SP spent (later section talks about it more), Alpha clone state and not perfect pilot skills. This forced me to modify the fit a bit.
Base
Paste base Povertila with Max-Alpha skills
Performance of this fit for Alpha pilots, even with max skills, is not the best. Due to lack of engineering skills the fit is not cap stable - which forces me to run Electrical weather exclusively. That's not bad 'per se', but is a limiting factor that I needed to take into account. I tried to modify this fit as little as possible though, because it means that all guides/strategies will be still valid.
Modifications
Paste AlphaGila with minimum skills
