"I started GK's with Razor spam but the games got very boring and fairly one sided. To give myself a challenge I decided to run a list with no transports and very little armor. This led me to a Deep strike list to try to compensate for the lack of mobility. I have not seen many GK DS lists that don't involve terminators/paladins. Please let me know what you think.

The short answer - eh. Deep-striking as an army doesn't work too well - one of the best armies to do this with (DoA Blood Angels) will only do it rarely. I think the better option if you don't want to go RazorKnights is keep your core and some Rhinos. You add mobility to your army but still have the option to deep-strike if needed. Yes you're using transports but you're not spamming them through the nose.
To open these points I'd be looking to take out the Dreadknight and I wouldn't be running Psybolt Ammo on the smaller GKSS - potentially give them a Psyback instead of a Rhino as well. MCing the Hammers on the larger Strike squads isn't going to amiss either.
If you're set even against that, well you'd want Purifiers or Purgation squads as much as possible so you can slap out more Psycannon shots when you land and that would really require a Grand Master for Grand Strategy which at 1500 is tough. I'd probably be looking at dropping the Dreadknight again, cutting back to 15 GKSS and grabbing a full Purifier squad with max psycannons. Use Grand Strategy to provide scoring on Purifiers/Interceptors. I'd still say it's weak but you at least have better firepower coming in on the drop - something you need for the deep-strike concept to work at its fullest (i.e. the meltaguns of DoA). Otherwise I'd be recommending adding in a few Rhinos - its not spammy but it does give you that mobility options.
