Resetting can be compared to Alien-swarm style resetting - no benefit beside looks.
Ramships - I always go for a certain amount of
Turbo Jet
A small amount of Liquid Rocket Engine (The fast booster things) - turned on by a hit on Q - they only serve to get over 300 mp/h, so the Turbojet gets started.
Same amount of cash that was put into TurboJets in Liquid rocket Engines - Turned on by hitting E
I have to tell you, the sound when I hit E, the Roaring of the Rockets, then the instant jump to 1500/2000 mph as you slam into the enemy - mhmm lovely.
As for Rockets, I've seen some people use very sleak designs (long, smooth, like (), which are extremely fast, but do "glitch" as you said.),
but I prefer to use the large, Druid Platform, with a ram, like this -> o]
I've used my turret-arm Tech to enhance this before, giving a cute crab like

Extremely Deadly - but very hard to get in range with all arms still attached - and you do catch every single bullet.
The other design i tried was a "Turtle" where it didn't care what side you use to ram.

While using this, with a turret + rockets can lead to a fun "Oh hey, he is slow and has no guns, pew pew, oh god he is flying right at me! - it just didn't do much damage when it actually rammed and was generally hard to employ, while taking very little punishment.
If there was a piece that lets you detached parts, the options would be endless. You could fire your Ram sled at people ... with GUNS ON IT!
(Deployable turrets and so on of course)
**+Edit
I started working on a design, much like you suggested, cat. I am however using a arm, to put the suicide charges far infront of me... so far I've only found out that:
a) you should not bind your turret controls to the same button as your rocket boost (whops)
b) you should turn auto-return off, on the turret.
c) AoE is pretty large, keep em at a distance.
**++Edit:
Clearly, planning to surive the suicide charge may have been a silly plan, any arm long enough (or armor) to let you stay unharmed, would also destroy any mobility (/server).
I liked the idea of having a tanky-platform and letting the charges go off one after the other, salvo style, destroying everything around you, faster then you are destroyed... but alas, the aoe is to big.
