Hey Vic, no need to be a complete @$$. I'm trying to help. So STFU and go back to mommy's teet.
Ok, so if you want a level 10 pet, you need a level 0 or level 1 shell. The level 2 shells (cloning 2) have too high of a risk of going level 11. The piket DNA is good stuff but it all comes down to combination.
Dune beetles (on Tatt) have excellent strength quality w/o going overboard. Pickets give good endurance (just normal pickets, not plain walkers or females). A Mountain Squill is good for aggression. Rock beetles and mound mites have good intelligence. The last DNA segment can really be whatever (loyality or whatever it's called) as long as it's below 300 points in both categories.
If you look at the 10 stats, they are grouped into 2 sets and each pair corresponds to a DNA profile slot. Anything above 500 will make the critter more than level 10 in most cases unless your gimp it with crappy DNA in another slot. So lets say I have 600/220 for strength, I would need to have 300/80 in aggression (just as an example).
Then comes the shell. The complexity SOMEWHAT dictates the level and strength of the creature. Anything with a complexity more than 24 will be very hard to get to CL10 with good DNA. There isn't a right or wrong creature. Just look at the DNA and try to manipulate the final product. Remember that ranged attacks, high resists and special attacks all add to overall CL.
