The apex suits have the same slot layout as their equivalent proto version BBBUUUTTTT!!!!! these apex suits are pre-fitted. This means that you CANNOT!!! change the equipment it comes with. A second thing is that the equipment the suit comes with are all at the basic level. So if it comes with a shield module that module is the same as the basic shield you buy at the market. So it is better than militia but equal to the basic level equipment in the market. Any skill you have skilled in also affects the apex suit and all racial bonus apply AS LONG AS you have skilled into them. So, if you want full dampening for the scout then you need to skill in the profile dampening skill.

Are these suits a good purchase? Meh I don't think they are great and they are very expensive. For example I would like to have the minmatar scout apex suit but if I wanted to buy it wthout using aurum would have to fight and win about 100 minmatar factional. That will take forever and thus the reason I haven't done it. That means that every time I die in a factional it is money wasted. On top of that the suit cost 10,000,000 isk. I figure that it would take me an additional 100 fights to get a return on my investment. SO, 200 battles is what would need to break even. My wife has a basic minmatar scout suit that cost about 10,000 isk. It only has basic equipment but, it does the job. I was using it the past few days and I made money on every single battle. Sure maybe not a whole lot but money never the less assuming a pay uot of at least 120,000 isk a battle then I can easily die 12 times and still break even.

My advice is that you find the google docs int he forums that tell you exactly what each suit comes with and see if it is worth the investment. I think that if you are going to pay with aurum you might consider a different bpo suit which at the very least allows you to put whatever equipment you want on it.
