@juanfranblanco No I don't think its our code. I notice in SignAndSendTransaction (with no type parameters), we can specify all Tx params, including gas and gasPrice but for the type-param version we can't. I've been able to get the non-type-param version to successfully send and execute transactions but the type-param requests won't go through. I really would love to be able to use the type-param version for methods that require struct input because that's a super super nice feature that will allow me to avoid having to manually encode these transactions (possibly, depending on the result of this discussion), which is something I would really really like to avoid for time's sake. Would it be possible to add support for Tx param editing (gas, gasPrice, value, etc) for the type-param version?
