Need some main weapon suggestions for hybrid school elisa..

..so i was planning to build a 20/20 w/ 36lk+16tgh school elisa hopper..and i need some suggestions on what handheld main weap should i use..that is less than 160 cost
..dont suggest pierce gun, i'd put it on instantly with no doubt only if i have it.
I was thinking about 1x/2x GRapidBeta tunes handy zook (i'd have enough capa to drop a capa cart for quick jump/other things if i dont putweap tunes on handy zook tho..but i guess it would be worse), no weapon tuned boost gun mod or combat mag. feel free to suggest other shop weapons too..
..actually i've heard that assist pump gun may have good potential..but idk how big the bullets actually are when the bot has 20 str so..idk
any ideas/suggestions?

EDIT: thanks to CS that applied 100% success rate to all +5cost+1stat tunes, i will abuse them from now on for my builds since im not that rich to afford those slut prrtectors, and therefore the number of slots might be one of the main problem in this build.
here are my two builds with handy zook/boost gun mod

Handy Zook ver:

boost gun mod ver:

Mu build used a pierce gun, but I had to remove it in order to give her a chance to shine in Beginner's Rule Set.
Instead, I use a Peacemaker which is easy to obtain from Super Uc Gara so I just slapped stat tunes on it because it already does well, even without weapon tunes, and gives me that competitive edge I need for 20/20 tec.
I don't know how big assist pump gun bullets get, but that could be another option.

Size comparison to Pierce Gun.

Can't get an excellent shot of pierce gun, because of the length of Pierce Gun:

Hitting things is pretty rewarding. I was landing around 17~30 at the time with single shots. I'll have to re-tune my Classic Elisa to double check.

@Akhenderson :O PIERCE GUN IS BANNED TOO? Nice!...uh i mean...aww Dx...and hmm i think ill try peace maker after i get one. ty.
@Kray ahh the bullet size sure is big but i doubt if it would work with only 270 speed (which is almost the same as a normal handy zook) and no rapid tunes..ty for the info though
