Stonetooth or no Stonetooth?

I have a base Dex of 40, and was planning on getting it to 60 for a stonetooth. I need to know whether doing this would be a good idea.

I already have a 115 attack stonetooth from my main.

If I were to not go stonetooth, what end game weapon would I be using (Considering maker skill coming etc.)

Keep in mind my funding....

Equips:

15/15 20 acc Zhelm

Deputy Star (Will get MoN)

Will have 15 Dex Battle Road 7 Acc

Either a 10 Dex or 10-12 accuracy shoe (Depending on if i go ST or not)

7 Dex Earring (will sell if i dont go Stonetooth.)

10 Dex/10 Str Icarus Capes

10 Att 2 Str 4 Dex Warrior Glove

If i were to go stonetooth, without all the equips, I have 100m left over. (Keep in mind I already have the stonetooth) Also know that I convert mesos into NX to make things easier since resources and equips are limited in Mardia. (About 20k NX)

If I were to rearrange things, I would have 50k NX, remember that this is without any weapons.

I am going to be using an average Screamer at 80 (around 103-105 att)

Now, does the extra strength that I will gain make up for the speed loss from the stonetooth

Also, what weapon(s) would I be using past DS.

Details and NX conversions would be great :p
