as a former graf user, who went to bauer nexus 8000, I didn't have a hard time switching. The only adjustment period was getting used to how ridiculously stiff they were so I just skipped the top lace loops.
I will suggest going with the skate that fits the best without baking and then baking will only accentuate that feel.
If the Tacks felt equal to the supreme, its all gonna come down to your decision and your wallet.
Bauer makes good skates, they have their issues like everyone and so do the tacks. The tacks aren't as stiff, but still offer great support and fit.
for skates you're coming off as a dude whos gonna buy this pair and use them for at least 3-5 years. maybe more. So take into consideration that although most current composite skates aren't as durable as your grafs they will give you a while for use.
Personally My nexus have lasted me well over a year of use and abuse and only have like 8 scuff marks and while reviewing them I stuck my feet in front of slap shots to try and test durability and protection. it hurt, but nothing ever broke.
Also take into consideration that Graf is no longer in Canada, but still operating out of Europe and will allegedly start exporting skates to the north Americas. In case you wanna check that out, (fyi graf is on clearance everywhere online too)
