SLIM is Momentum Disc Golf´s second mold and first putter. Slim is also a good description of the disc. Flight specs:  2  4  -3  0.

With a low height it is different from many other putters on the market and suitable for small hands as well as large hands. The thin feeling of the disc is made to give you better control over your release point during putting, increasing your accuracy. The tighter grip you get on this putter, compared to most other putters, will make it easier for you to spin it faster. The faster spin will decrease the amount of flutter and also increase your accuracy. 

SLIM is very understable and maybe not a good disc for longer drives. The main use is within 20 meters from the basket. SLIM can also be used as a utility disc for back-hand, fore-hand and over-hand shots where the under-stability comes to good use, for precision shots up to 50 meters.
