Dynamic SOAP Call Client Testing

Hi,

I would like to test SOAP calls (SOAP XML) using SOAP Client.

Could you please help me to guide any nice SOAP tool and its configuration with CRM 2015?

I am using SOAPUi but its not working property with optionsetvalues.

Below is the code to create record in crm with option set. it was working fine now its not. I don't think it is issue with my SOAP XML but I am positive issue is with my SOAP client. Could you please help me to find correct SOAP client or correct my configurations.

<con:KeyValuePairOfstringanyType>
            <sys:key>new_leadtype</sys:key>
            <sys:value i:type="con:OptionSetValue">
              <con:value>863960005</con:value>
            </sys:value>
          </con:KeyValuePairOfstringanyType>

SOAP Header I set for CRM 2015
