I'd just use both, since you seem thorn about it. Some niss' if you scroll them well from the start (20) with good gear which may have good spars/diamonds and maybe even a brooch will still be just as useful. All these things you can get without spending money in the mall. Brooch you may be able to get if you trade for it in game. It can all work out especially if you have it on a fire character then I see no problem with it.

Some times you need one pet for something and other times its useful to have another type for something else like questing. Often in the middle of a quest if a pet dies and I have no time to revive them or heal them I just swap them for a new pet who is just as useful. The Only problem with this is when it comes to training/lvling each it takes longer.

Where as you would have 1 pet and have them be same lvl as you. (example you are 160 pet is 158) you would instead have 2 pets that are almost less that half. (example you are 160. pets are 113 and 132)

You can always focus on 1 and then when you get tired of them or when they reach the desired lvl you hope for or maxed lvl. You can then switch and lvl a new one.

This way your scrolls, time spent and hard work doesn't go to waste. Mean while just do 15round, NT, quests, instances or any other events that will give you eggs and tokens. That way you can have a random chance to get more scrolls. And with the fun tokens you can try the mall/carnie games to get spars, crits, IM gears or even pet scrolls. If you fail you can still save up the carnie tickets to get scrolls from the lady in carnie. I think its like 160 or 130... I don't buy from the carnie lady so I'm not sure. Just go talk top her and choose "prizes over 110 etc..." and it should say.
