I need to educate myself about the offer I received. Tyler County, WV

I’m just learning about all of this since Antero sent me an offer to lease or sell about 3 weeks ago. In fact I let the lease go unsigned by the “due date” as I’m not educated enough just yet. Background: WV Tyler County, 13 acres. Was offered 300 signing bonus and 15% royalties. I’ve learned a lot on this site before posting this but I still have questions. Should I be trying to find the landman for other companies and seeing what they’ll offer (and how do I get that info?) or just negotiate with Antero for a better deal? Also, it seems there was a lot of talk and interest in WV back in 2018. I see in old posts the offers were much higher. Should I be going off those numbers or not as this is new drilling?
