When you guys switch gear, how long are you trying it before you decide you don't like it? Switched from ace to indy and its been two weeks and I don't know if I'm going to stay with it
I think there is a point where you realise something is just not working no matter what, at which time it is almost silly to keep going with it if it is going to make you hate your ride.
That is different to setting up a new board or whatever and just taking time to adjust to it, of which I know the difference, eg this is feeling a bit weird, but I will stick with it, vs this sucks and I hate it and don't even want to skate...
Any new thing, but especially trucks, can be a deal breaker if you don't wear them in well to start with, eg just roll around for a good while, break in the bushings, or swap them out if they are not working, because most take a bit to get right, or in the case of going from Ace to Indy, if they are not turning as much as Ace, take out the bottom washer on the Indy bushings and see if that makes them a bit more turny like Ace.
I usually ride Indy and have done for decades, had a session or two on boards with Ace trucks, then going back to my other board with Indy trucks, they felt like they didn't want to turn at all and were just wrong, so then it took a bit to get back to the normal feel there.
Other than that, no truck of a different brand is going to feel instantly awesome, unless you are a skateboard magician or something like that, but try to work out what it was about the different truck that worked or now doesn't work for you. I could guess the following:
Indy you might get ghost pop as they are taller and further out than Ace.
Indy don't turn half as quick as Ace, especially if you rode them fairly loose - take out a bottom washer and see how that feels, so you can always just put it straight back in without issue.
New truck grind is always going to be more slippery than old worn in truck grind - scratch them up a bit on a rough curb if they feel too slippery new.
Work in the bushings a bit - stand on the board feet pointing towards nose or tail on either edge over one truck and step left right left right up and down to break in the bushings sooner, then repeat on the other truck. Often do this on carpet or something just to avoid slipping out, but it breaks in bushings really well.
