I don't know exactly what's going on w/ Juno and Suncoast bats here, but I'll briefly discuss my Juno experiences and thoughts. When 240s first came out (2021) I bought a Juno MR1 to take to a conference event in TX. It was one of the first Junos made. Very durable bat, and it tests at 300ish. Later that year I bought an MR2. Very similar, tests at 275. Later on I bought a MK18 used that tests at about 270.
Juno's early models test high, and are very durable. Now, a lot of their newer stuff seems to start at very low compression, and some have even been known to fail with the wrapper on them. For what Junos go for pricewise, I'd NEVER buy any of their newer stuff. WAY too fragile.
Suncoast bats simply aren't durable. A lot of guys I know swing them, and they fail compression testing within a couple tournies.
